Nivada offers a range of dive watches and other models - including chronographs, sport watches, and classic designs. The brand's collections are defined by functional design and high manufacturing quality. Nivada has experienced a remarkable revival in recent years, reintroducing iconic historical models and leaning into its archives and retro aesthetics to captivate vintage enthusiasts and modern collectors alike. From standard chronometer functions to tachymeters and navigation chronometers, the Chronomaster is built for versatile men who want a watch that keeps pace with them in style. This stunning Singer Paul Newman watch pays tribute to the Newman legacy through its distinctive typography, faithfully recreated from the original SINGER design for this reissue. The model ships in a box with five interchangeable bezels to suit every mood without compromising the brand's legendary durability. The silver-toned case is crafted from brushed and polished 316L stainless steel in a round shape, measuring 38 mm in diameter and 13.75 mm thick - dimensions that sit perfectly on men's wrists. The aluminum bezels are bidirectional with click stops and superluminova markers, graduated with a minute scale and a GMT complication for added functionality. A double-domed sapphire crystal protects the dial from scratches and shocks. The crown and two pushers at 2, 3, and 4 o'clock handle hand and counter adjustments. Finally, this watch is available with either a transparent sapphire crystal caseback or a solid steel caseback via the dropdown menu. The screwed caseback ensures water resistance of 10 ATM.
The Singer Paul Newman dial from the Chronomaster collection was limited to just 50 pieces at launch. Closely tied to Paul Newman's iconic aesthetic, it sold out in a record 24 hours - cementing its status as a must-have among vintage watch enthusiasts. The white dial features a matte finish that completes its timeless design. The dial edge is lined with a tachymeter scale and a minute track for easy time reading. These markers, along with the black hour indices, are swept by three hands displaying the hours, minutes, and seconds of the chronograph. The two main hands feature a superluminova coating for enhanced legibility in low-light conditions, while the two subdials at 3 and 9 o'clock track the 30-minute and 60-second counters. The brand name is printed at 12 o'clock and the collection name at 6 o'clock.
Powering this timepiece is a Swiss-made mechanical movement. More precisely, the Landeron 70 caliber ensures the reliability of the analog display while driving the counters.
This timepiece ships with three interchangeable straps so you can switch up your style whenever the mood strikes:
The first strap is crafted from silver-toned 316L stainless steel. Its rice-grain link texture, combined with polished and brushed finishes, enhances its aesthetic appeal. It fastens with a deployant clasp measuring 18 mm wide.
The second strap is crafted from perforated black bovine leather, allowing the wrist to breathe for lasting comfort. Perfect for polished looks, its design is finished with tone-on-tone stitching.
The third strap is made from perforated black rubber, featuring a braided pattern that pairs effortlessly with any outfit. It's the ideal choice for sports and outdoor activities.
Note that these last two straps fasten with an 18 mm steel pin buckle, and all three straps share a 20 mm lug width.
With a water resistance of 100 meters - or 10 ATM in watchmaking terms - this bold timepiece holds its own at black-tie events and in the water alike. Feel free to wear it in the shower, the bath, or during your swim sessions (even vigorous ones!). That said, our watchmaking experts advise against using this model for scuba diving - whether freediving or with tanks - or with high-pressure washers. Remember: shower, bath, and swimming only, and never operate the pushers or crown while submerged!
